Headphones featuring their own volume and playback controls are a grand convenience since it means you can leave the device you're listening to buried in your pocket. But instead of placing a subtle set of buttons on the cord, Denon's new AH-D400 Urban Raver cans feature a large easy-to-access volume knob right on your ear.

It certainly makes it easy to quickly adjust the volume without having to fumble or feel your way over a set of tiny buttons, but the problem is, that knob is just as easy for someone else to mess with too. But is that a reason to completely dismiss a pair of headphones that also come with 50mm drivers and a built-in amp for added bass, and work with an accompanying iOS/Android app for configuring custom EQs? Absolutely not. But their $400 price tag and battery that has to be recharged every 12 hours might be.
